make sure you have some realy realy comfy shoe's, your going to need em. get ya self down to old town one evening, there is a bit of a funfair and some nice little shops. not sure how you would find out but on some nights, there is an old school car show and on other nights they have bikes. plus there is a longhorn's just over the road and it's mint (if your not veggie)
eating out: i found golden coral to be the best buffy style place, there are a few to chose from, sizlers and ponderosa but for me, choice and service is a lot better at golden coral.
shopping: when visiting the mals, go to the customer services/relations and collect a discount book, they give you 10-15% off all the major store's.
also try the flea markets, you can get some good deals on gifts n stuff, be care full with the electricals though, some of em are snide (any one want to buy a tomtom1)
ps: wallmart cheese cake is the best in the world.
